Classic Promise Cushion-Cut Sapphire Ring

Please contact us directly should you require a ring in a size that is not shown on the website.

With the captivating depth of sapphire waters and the timeless allure of fine craftsmanship, the Classic Fuster Promise Ring is a striking celebration of strength and elegance. At its heart lies a remarkable 6.9 carat cushion-cut sapphire — an intense, velvety blue gem held delicately in refined prongs, radiating quiet power and natural brilliance.

Framed by two tapered baguette-cut diamond side stones and set in luminous white gold, this composition reflects the signature restraint and refinement of Fuster’s legacy.

With a total weight of 7.5 carats, this heirloom-quality creation speaks to those who seek more than beauty — they seek rarity, permanence, and meaning.

Each Fuster creation is unique. As a result, size, carat weight and stone qualities can vary slightly from one to another. For detailed information, please contact us or book an in-store appointment.
